This workshop, suitable for both beginners and experienced practitioners, will provide students the opportunity to print intuitively in the gum bichromate process.  They will be introduced to the history of the process, view notable examples, and learn through demonstration and the making of prints.  Participants will be using just one high-contrast negative, printing in successive layers of color and brushing away parts of each layer to reveal underlying colors.

Paper, chemistry, and watercolor pigments will be provided by The Halide Project.

  • Please note that this workshop is open to those interested in working from digital negatives, however large format (4x5 or larger) B&W film negatives high in contrast will also work well.

  • For those working from digital negatives, please bring your own, or you can provide two digital files in advance that will be made into negatives for class.  (You will be given the option to pay for the two negatives upon registration. The cost is $30 for both.) 

Masks optional.
